The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up at Jaconé over the next couple of weeks.
It starts slow. Wednesday afternoon the 22nd is the first real chance. Wave height is around 5ft from the ENE with a short period of 8 seconds, and the wind is a light cross-off from the ESE. Conditions are clean, but the energy is weak (292). Water temp is 72°, which is pretty average for this time of year. Not a standout, but it’s surfable.
After that, it goes flat. From Thursday the 23rd through Saturday morning the 25th, it’s poor. Swell drops below 3ft, with cross-on or onshore wind making it choppy. That’s about four days of nothing worth getting wet for.
Saturday afternoon the 25th brings a pulse of S swell at 4ft with a 10-second period, but it’s cross-on and there’s a risk of thunderstorms. The energy is moderate (285), but the wind ruins it. Sunday the 26th has a 4-5ft S swell with a long 14-second period, but it’s cross-shore or cross-on, so only marginal. Energy is strong (543), but the direction isn’t doing us any favors.
Monday morning the 27th is the real deal. That S swell is still 3ft with a 12-second period, and the wind swings offshore from the ENE. It’s clean. Energy is solid (326). Tuesday morning the 28th is similar: offshore NE wind, clean, with 2ft of S swell at 12 seconds. Energy is 277. These two mornings are the best in the first week. Not huge, but clean and lined up.
Wednesday the 29th is glassy in the morning, but the swell is tiny at 2ft (115 energy). That’s a longboard session. Then it’s another poor run through the end of July and into August, with onshore winds and small, weak waves.
There’s a long-range possibility on the 5th of August, a Wednesday morning. That’s two weeks out, so keep it in the back of your mind. It shows a 4ft S swell at 11 seconds with offshore ENE wind. Energy is 460, which is strong. That’s a proper groundswell and it’ll be clean. Thursday morning the 6th also has offshore wind and a 3ft ESE swell, but the period drops to 9 seconds, so it won’t have the same power.
The standout is Monday morning the 27th and Tuesday morning the 28th. Clean, offshore, decent energy. The long-range 5th of August is worth watching, but it’s a ways off.
Crowds at Jaconé can be a problem sometimes, so on the clean days, expect some company.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
